COLTON (CBSLA.com) — A family is outraged that a suspected drunk driver who killed two young girls and a grandmother in a January car crash still hasn’t been charged in their deaths.

Kylan Allen, 12, Haven Penman, 13, and Allen’s 56-year-old grandmother, Le Mason, were on their way to a church event on Jan. 18 when Mason’s vehicle collided with another car on Main Street and Placentia in Colton.

At the time of the crash, police said the driver of the other car, 29-year-old Michael Hughes, was drunk.

Hughes, who has a lengthy record of traffic violations, was arrested on suspicion of driving under the influence and murder, but the San Bernardino District Attorney’s Office is still investigating the case.

Although there are reports Mason made an illegal turn or didn’t yield, Penman’s loved ones said it doesn’t matter because they believe Hughes was under the influence. The 13-year-old’s family is encouraging prosecutors to charge the now-free man.

“What I would say to Michael Hughes is if he has a soul, guilt is going to get him. If not, there’s nothing I can do to make him feel,” said Penman’s mother, Simone Daly.

Penman’s aunt, Valerie Wates, said, “I just wish he would feel sorry for what he’s done. It seems like he has no remorse.”
